Metabolite Identification
Common NameNoralfentanil
DescriptionNoralfentanil is a metabolite of alfentanil. Alfentanil (R-39209, trade name Alfenta, Rapifen in Australia) is a potent but short-acting synthetic opioid analgesic drug, used for anaesthesia in surgery. It is an analogue of fentanyl with around 1/4 the potency of fentanyl and around 1/3 of the duration of action, but with an onset of effects 4x faster than fentanyl. It is an OP3 mu-agonist.
